Symbiosis refers to a prolonged and close interaction between two or more different biological organisms. These relationships are fundamental to ecological dynamics and can manifest in several distinct forms. Mutualism occurs when both participating species benefit from the interaction, such as in certain root-microbe associations. Commensalism describes a relationship where one species benefits while the other is neither harmed nor helped. Conversely, parasitism involves one organism, the parasite, deriving sustenance from another, the host, often causing detriment to the host. The study of these interactions illuminates critical aspects of biological adaptation, nutrient cycling, and ecosystem stability.
